We might still be waiting for the first paper plane to carry a human from A to B, but a German-made paper boat has floated successfully down the London Thames, with the suitable name of "HMS Origami."

German "artist" Frank Bolter cheated in some way, as the paper he used wasn't normal construction paper you and I made our boats from as kids—it was actually the tougher sort, which is used for juice boxes and other drinks cartons. Once made, it measured 5.4m in length—just long enough for a Daily Mail hack to hop inside and sail it down the river. [Daily Mail]
